Minimally invasive enucleation of pancreatic tumors has become a focal topic in the field of pancreatic surgery. This technique, which allows for complete tumor removal while preserving maximal pancreatic function, has seen widespread application in clinical practice in recent years. Preoperative evaluation is essential, requiring a thorough assessment of the necessity, feasibility, and appropriateness of surgery, and a careful choice between follow-up observation, parenchyma-sparing resection, or radical resection. If the lesion carries a potential risk of malignancy, radical resection, such as pancreaticoduodenectomy, should be performed. During minimally invasive local resection, selecting an appropriate surgical approach, accurately localizing the tumor, protecting the main pancreatic duct (MPD), and effectively repairing and reconstructing the MPD in case of injury are key to ensuring both surgical safety and efficacy. In addition, pancreatic wound management and the long-term prognosis of patients who undergo MPD repair and reconstruction are also areas of significant concern.

Pancreatic cancer is a highly malignant tumor,and its incidence rate has been slowly increasing since 2000.Although the improvement of diagnosis and treatment has led to an increase in the five-year survival rate of pancreatic cancer compared to 50 years ago,it remains one of the discouraging tumor diseases regarding its prognosis.In 2024,many achievements were made in the research of early screening,disease mechanism,clinical diagnosis and treatment of pancreatic cancer,showing a good prospect for clinical application.In early screening,artificial intelligence(AI)technology has empowered early diagnosis and screening of pancreatic cancer,pushing clinical diagnosis and treatment to a new level.Additionally,improvements in the accuracy of technologies such as liquid biopsy have provided new directions for early screening of pancreatic cancer.In terms of research on disease pathogenesis,3D genome mapping technology has revealed the polyclonal origin and genetic heterogeneity of pancreatic intraepithelial neoplasm(PanIN).In basic research,a branched organ simulation system that mimics the unique structural characteristics of pancreatic cancer provides a new model for in vitro studies of pancreatic cancer.Lactate,an important tumor metabolite,links the metabolic microenvironment of pancreatic cancer with epigenetic changes,revealing potential therapeutic targets.Defects in the histone H3K36 trimethyltransferase SETD2 contribute to endogenous epigenetic dysregulation in pancreatic cancer and promote mitochondrial oxidative phosphorylation(OXPHOS)and tumor progression.The platelet-derived growth factor receptor(PDGFR)axis,which facilitates communication between stromal cells and cancer cells,forms a bidirectional secretory circuit and may become a new therapeutic target.Chimeric antigen receptor macrophage(CAR-M)therapy targeting the tyrosine kinase receptor c-MET demonstrates potential for synergistic enhancement with chemotherapy drugs.Macrophages in the pancreatic cancer microenvironment promote the development of pancreatic cancer cachexia through the CCL5/TRAF6/nuclear factor-κB(NF-κB)pathway,suggesting that macrophages could be an effective target for predicting and intervening in the development of pancreatic cancer cachexia.In terms of advancements in diagnosis and treatment,surgery following neoadjuvant chemotherapy can improve overall survival(OS)in resectable and borderline resectable patients,but further optimization of neoadjuvant chemotherapy protocols is needed.The first clinically effective KRASG12D-targeted drug has been reported,and research on inhibitors of a wide range of KRAS mutants is continually emerging.Patient stratification based on glycolysis-related scores(GRS)can further guide the selection of treatment protocols."Intelligent exosomes"(ExoSmart)enhance cellular uptake capacity to assist in improving chemotherapy efficacy.The implementation of clinical trials combining immunotherapy with chemotherapy is expected to synergistically improve the efficacy of pancreatic cancer treatment.Pembrolizumab and anlotinib combined with albumin-bound paclitaxel/gemcitabine(PAAG)have shown great efficacy and safety in first-line treatment of metastatic pancreatic cancer(mPC)patients.The cancer vaccine ELI-002 2P,which targets KRAS mutation-encoded neoantigens,can induce an antitumor immune response.Oncolytic adenovirus therapy can synergistically improve the efficacy of treatment in advanced pancreatic ductal adenocarcinoma patients when combined with chemotherapy.This article reviewed the latest major progress in the field of basic research and diagnosis and treatment of pancreatic cancer in 2024.

Objective:To analyze and validate the reliability and validity of the social skills improvement system-rating scales Chinese version (parent version) (SSIS-RS-C) in middle school students.Method:A total of 1 486 parents of middle school students were recruited according to the cluster sampling method.The social responsiveness scale and strengths and difficulties questionnaire were used as criterion validity tools.A retest was conducted one month later.SPSS 27.0 was used for descriptive statistics, item analysis, internal consistency test, test-retest reliability test and criterion validity test. AMOS 24.0 was used to perform confirmatory factor analysis .Results:Item analysis indicated significant positive correlations between each item and the subscales ( r=0.293-0.782, all P<0.01), with significant differences in scores between high and low groups ( t=10.079-37.038, all P<0.01).Confirmatory factor analysis supported a seven-factor structure for the social skills subscale(communication, cooperation, assertion, responsibility, empathy, engagement and self control) and a five-factor structure for the problem behavior subscale (externalizing, bullying, hyperactivity/inattention, internalizing and autism spectrum) of the SSIS-RS-C.There was a positive correlation between the social skills subscale and prosocial behavior ( r=0.637, P<0.001), and between the problem behavior subscale and social impairments and difficult behaviors ( r=0.765, 0.688, both P<0.001).The Cronbach's α coefficients for the total scale, social skills subscale and problem behavior subscale were 0.934, 0.972 and 0.963, respectively.The test-retest correlation coefficients for the total score and the two subscales were 0.665, 0.871 and 0.598, respectively (all P<0.001). Conclusion:The SSIS-RS-C demonstrated good reliability and validity in the Chinese adolescent population.

In addition, pancreatic wound management and the long-term prognosis of patients who undergo MPD repair and reconstruction are also areas of significant concern.

The incidence and detection rates of benign and low-grade malignant pancreatic tumors have risen yearly.For patients with such tumors,traditional radical resection procedures often result in excessive loss of normal pancreatic parenchyma,leading to complications such as postoperative insufficiency of both exocrine and endocrine functions.Studies have shown that functional-preserving surgeries,such as minimally invasive enucleation or partial resection surgeries,can maximize the protection of patients'pancreatic function and improve long-term quality of life.However,for some tumors deep within the pancreatic parenchyma,accurately locating the tumor and protecting the pancreatic duct pose challenges.Intraoperative ultrasound(IOUS)has become an ideal intraoperative imaging tool,often referred to as the surgeon's"third eye"because of its portability,ability to provide real-time high-resolution information,non-reliance on ionizing radiation,and the fact that it does not require special patient preparation.With advancements in technology,the application scope of IOUS has expanded beyond its initially limited diagnostic role to various surgical applications,including identifying non-palpable lesions,guiding surgical strategies,and staging tumors.In the current era of minimally invasive and precision surgery,the proficiency of surgeons in using IOUS has become an important issue.This article reviews the history of IOUS applications,summarizes the advantages and basic usage methods of robotic IOUS,and shares techniques for applying IOUS in robot-assisted precise resection of pancreatic tumors.

While neuroblastoma accounts for 15% of childhood tumor-related deaths, treatments against neuroblastoma remain scarce and mainly consist of cytotoxic chemotherapeutic drugs. Currently, maintenance therapy of differentiation induction is the standard of care for neuroblastoma patients in clinical, especially high-risk patients. However, differentiation therapy is not used as a first-line treatment for neuroblastoma due to low efficacy, unclear mechanism, and few drug options. Through compound library screening, we accidently found the potential differentiation-inducing effect of AKT inhibitor Hu7691. The protein kinase B (AKT) pathway is an important signaling pathway for regulating tumorigenesis and neural differentiation, yet the relation between the AKT pathway and neuroblastoma differentiation remains unclear. Here, we reveal the anti-proliferation and neurogenesis effect of Hu7691 on multiple neuroblastoma cell lines. Further evidence including neurites outgrowth, cell cycle arrest, and differentiation mRNA marker clarified the differentiation-inducing effect of Hu7691. Meanwhile, with the introduction of other AKT inhibitors, it is now clear that multiple AKT inhibitors can induce neuroblastoma differentiation. Furthermore, silencing AKT was found to have the effect of inducing neuroblastoma differentiation. Finally, confirmation of the therapeutic effects of Hu7691 is dependent on inducing differentiation in vivo, suggesting that Hu7691 is a potential molecule against neuroblastoma. Through this study, we not only define the key role of AKT in the progression of neuroblastoma differentiation but also provide potential drugs and key targets for the application of differentiation therapies for neuroblastoma clinically.
